A machine for producing products such as ice cream, frozen beverages or granita. An example of the machine comprises a tank with a tap for dispensing a product. A cylinder with a substantially horizontal axis projects from a rear wall inside the tank. The cylinder forms the evaporator of a refrigerating circuit. A mixer element around the cylinder rotates coaxially with the cylinder axis. A motor unit is connected to the mixer element via a drive shaft passing along the axis of the cylinder. The drive shaft connects to the mixer element at one end of the cylinder opposite the rear wall. The motor unit comprises a final reduction stage in alignment with the cylinder axis, a motor arranged at an angle with respect to the cylinder axis and substantially parallel to the rear wall, and an angular drive between the final reduction stage and the motor.

1. A machine for producing and dispensing a product including, or similar to, ice cream, a frozen beverage or granita, the machine comprising: a tank for containing the product, the tank provided with a tap for dispensing the product, wherein inside the tank there projects from a rear wall a cylinder which has a substantially horizontal axis and which forms an evaporator of a refrigerating circuit of the machine for cooling the product in the tank;a mixer element for stirring the product, the mixer element having a rotation axis, the mixer element being present around the cylinder so as to rotate coaxially with the axis of the cylinder;a motor unit arranged outside the tank which rotates the mixer element using a drive shaft with an axis which passes along the axis of the cylinder and which is connected to the mixer element at one end of the cylinder which is opposite to the rear wall, the drive shaft being coaxial to the rotation axis of the mixer element, wherein the motor unit comprises: a final speed reduction stage arranged coaxial with both the drive shaft and the rotation axis of the mixer element, the final speed reduction stage comprising a input shaft and a output shaft which have rotation axes parallel to each other and with the drive shaft and a speed reduction rate from the input shaft to the output shaft, the output shaft being coaxial with the rotation axis of the mixer element and connected to the drive shaft;an electric motor having a shaft, wherein the electric motor projects laterally with the axis of the electric motor shaft substantially transverse to the axis of the drive shaft; andan angular transmission stage interconnecting the input shaft of the final speed reduction stage and the shaft of the electric motor. 2. The machine according to claim 1, wherein the motor unit is at least partially housed inside the cylinder through the rear wall. 3. The machine according to claim 1, wherein the electric motor is arranged with the axis of the electric motor shaft substantially parallel to the rear wall. 4. The machine according to claim 1, wherein the inner wall of the cylinder is lined with a layer of heat-insulating material in which a seat is formed for an output end of the motor unit and for receiving the coaxial drive shaft. 5. The machine according to claim 1, wherein the angular transmission stage comprises an input worm which engages with an output crown gear. 6. The machine according to claim 1, wherein the final reduction stage comprises an epicyclic reducer. 7. The machine according to claim 6, wherein the epicyclic reducer is a two-stage epicyclic reducer. 8. The machine according to claim 1, wherein the angular transmission stage is an angular speed reducer. 9. The machine according to claim 1, wherein the motor unit comprises flanges projecting laterally from the final reduction stage for fixing thereof in the machine. 10. The machine according to claim 1, wherein the motor has a rear part, the rear part of the motor directed upwards and provided with a rotating fan which blows at least partially into an air conveyor which emits an air flow onto the outer wall of the tank. 11. The machine according to claim 1, wherein the speed reduction rate between the input shaft and the output shaft equals a first speed reduction ratio. 12. The machine according to claim 1, wherein the angular transmission stage comprises an input and an output, the input of the angular transmission stage being coaxial with the electric motor shaft, the output of the angular transmission stage being connected to the input of the final reduction stage.
